JERUSALEM (AP) — The Israeli military struck a series of Palestinian militant targets in the Gaza Strip on Tuesday, damaging smuggling tunnels and suspected weapons sites. Palestinian officials said 19 people were wounded.

Israel's volatile border with Gaza has been largely quiet since an overwhelming Israeli military offensive two years ago. But Israeli officials say Gaza's ruling Hamas militant group has recovered from the fighting, and the area has begun to heat up in recent weeks.

Palestinian health official Adham Abu Salmia said one man was critically wounded in a border clash Tuesday.

The Israeli army confirmed the incident, saying it opened fire at a group of militants who were about to fire a missile at a tank.

BU MARIEM, Libya (AP) — An American fighter jet crashed in Libya's rebel held east, both crew ejecting safely as the aircraft spun from the sky during the third night of the U.S. and European air campaign. Moammar Gadhafi's forces shelled rebels regrouping in the dunes outside a key eastern city on Tuesday, and his snipers and tanks roamed the last major opposition-held city in the west.

WASHINGTON (AP) — For two years, the Obama administration has had a relationship of convenience with Yemen: The U.S. kept the Yemeni government armed and flush with cash. In return, Yemen's leaders helped fight al-Qaida or, as often, looked the other way while the U.S. did.

That relationship is about to get a lot less convenient.

Of all the uprisings and protests that have swept the Middle East this year, none is more likely than Yemen to have immediate damaging effects on U.S. counterterrorism efforts. Yemen is home to al-Qaida's most active franchise, and as President Ali Abdullah Saleh's government crumbles, so does Washington's influence there.

AJDABIYA, Libya (AP) — Moammar Gadhafi's forces shelled rebels regrouping outside a strategic eastern city on Tuesday and his snipers and tanks controlled the streets of the last opposition-held city in the west, signaling a prolonged battle ahead. An American fighter jet crashed over North African country, both crew ejecting safely.

The U.S. Africa Command said both crewmembers were safe after what was believed to be a mechanical failure of the Air Force F-15.

Disorganization among the rebels could hamper their attempts to exploit the air campaign by U.S. and European militaries. Since the uprising began on Feb. 15, the opposition has been made up of disparate groups even as it took control of the entire east of the country.

AJDABIYA, Libya (AP) — Moammar Gadhafi's forces lobbed artillery shells at rebels regrouping outside a strategic eastern city, forcing a band of fighters to scatter and signaling a prolonged battle as the U.S. said it was shifting its focus to widening a no-fly zone across the North African country.

The first round of the allied assault over the weekend smashed a column of regime tanks that had been moving on the rebel stronghold of Benghazi in the east, reversing the government's advance and allowing the rebels to barrel to west, vowing to break a siege on Ajdabiya, a city of 140,000 that is the gateway to the east.

FUKUSHIMA, Japan (AP) — Weariness and anxiety percolated Tuesday among people who left their homes near Japan's radiation-shedding nuclear complex as workers tried urgently to cool an overheated storage pool and methodically to reconnect critical cooling systems.

In another day of progress and setbacks, a pool holding spent nuclear fuel heated up to around the boiling point, a nuclear safety official said. With water bubbling away, there is a risk that more radioactive steam could spew out. "We cannot leave this alone and we must take care of it as quickly as possible," said the official, Hidehiko Nishiyama.

DETROIT (AP) — General Motors Co. on Monday is halting some production and temporarily laying off workers at a Buffalo, N.Y., engine plant, another sign that Japan's disaster is affecting automakers around the globe.

GM is suspending production of engines built at its Tonawanda plant for the Chevrolet Colorado and GMC Canyon compact pickups, which are assembled at a GM factory in Shreveport, La. GM shut down its Shreveport operation this week because of a shortage of parts from Japan.
